get_journal

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and idempotentHint. The description adds value by specifying the contents (snapshots, runs, tags, notes) beyond what annotations provide. However, it does not disclose limitations or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence of 14 words, front-loaded with the main purpose. No extraneous information; every part is essential.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (1 parameter, no nested objects, output schema exists), the description is mostly complete. It lists the journal components, though it omits prerequisite conditions (e.g., strategy must exist) and does not clarify if the output is paginated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one parameter (strategy_id) with 0% description coverage. The description merely restates that it is 'for a strategy_id' without explaining its format, source, or constraints, leaving the agent with insufficient semantic information.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get'), the resource ('full journal'), and the qualifier ('for a strategy_id'). It lists included components (snapshots, runs, tags, notes), distinguishing it from siblings like list_journals which likely provide a summary.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. While the description implies it is for detailed retrieval of a single strategy's journal, it does not mention exclusions or alternatives like list_journals or get_strategy.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
